Do you mean 'Are train driving jobs still just as secure as before the pandemic?'
If so, prepare for strongly held opinions from people that they are and also are not. Worth considering the main elements of security also, is the position itself secure (redundancy risk), is it's number of hours predictable (overtime or hours cuts), and is the rate of pay going to go down?
On the railway some people argue that the general trend is reversed, and that it is easier to make people redundant than reducing pay. However, of all roles in TOCs, train drivers are the least likely to be hit with compulsory redundancies.
